Leakage.
It should be pointed out that there is no concrete shape regulation for wedge-type shape, as long as so wide shape in the narrow one end in one end
Shape can be regarded as wedge shape.
It may also be noted that pipeline is divided into water inlet pipe 103 and outlet pipe 104.
In the alternative of the present embodiment, wedge shape valve core 2 and the contact surface of pipeline end face are ground through precision.
When wedge shape valve core 2 is moved to low side in cavity 101, wedge shape valve core 2 will be contacted with pipeline end face, this is contacted
Face is through precision milled processed, it is ensured that the leakproofness of valve prevents from revealing.Distinguish the gasket of the prior art, the pad of the prior art
Piece is easily corroded, once corrosion valve integrally will be unable to ensure sealing performance.
It should be pointed out that in actual use, wedge shape valve core 2 is only needed the contact surface and and chamber with 103 end face of water inlet pipe
101 base contact surface precision of body is ground.
In the alternative of the present embodiment, catch means are arranged in lock-bit hole 3；
Catch means are horizontal positioned；
Catch means are arranged above pipeline.
It should be pointed out that being arranged catch means above pipeline, reasonable layout is carried out, keeps catch means normal
It uses, while horizontal positioned catch means, catch means is made preferably to reach lock-bit effect.
It may also be noted that catch means are used to lock wedge shape valve core 2, stationary wedge spool 2.
In the alternative of the present embodiment, catch means include screw 301, lock-bit spring 302 and locking pin 303；
